ABSTRACT:
A brake system and torque feedback controller is provided which utilizes low torque cutout rather than low speed cutout. The low torque cutout is further improved by gradually transitioning between torque feedback and open loop control over a range of torque. The controller allows torque compensation operation to zero wheel speed, and avoids discontinuities in braking regardless of time or torque level. The controller allows a brake to fill and engage the wheel before the full feedback signal is presented to the controller so as to eliminate the phenomena of grabby brakes.
